项目摘要

We studied environmental temperatures and biological responses as well as occurrence of death from heat stroke in the summer.(1) Heat stroke during exercise occurred in Hokkaido at a temperature 2-3℃ lower than in Honshu, and the degree of adaptation of people to high temperatures is considered to be different between the two regions.(2) In Kobe, heat stroke and dehydration occurred frequently in those aged 65 years or above according to the records of emergency care. Their frequency increased when the temperature was about 2℃ higher than on the previous day as well as on hot days.(3) Although the outdoor temperature is high during the daytime and low at night, some people live and work in air-conditioned rooms that are cooler during the daytime than at night This difference between controlled indoor temperatures and outdoor temperatures widens the temperature range that we experience.(4) The relationship between the heart rate and the oxygen uptake was studied in summer during exercising (ergometer pedaling) indoors (20-25℃ and outdoors (30-35℃), and biological responses during exercise were evaluated. Although there was no change in the oxygen uptake at the same exercise intensity, the heart rate was increased during outdoor exercise presumably due to dilation of cutaneous vessels in response to a high temperature. In daily living during summer, sudden temperature changes between the cool indoor and hot outdoor environments are considered to a problem for health.

我们研究了夏季的环境温度和生物反应以及中暑死亡的发生情况。(1)北海道发生运动中暑的情况比本州低2-3℃，以及人们对运动中暑的适应程度(2)根据急救记录，在神户，65岁以上老年人中暑和脱水的发生率在气温升高2℃左右时增加。与前一天相比(3)虽然室外温度白天高、晚上低，但有些人生活和工作在空调房内，白天比晚上凉爽。这种受控室内温度与室外温度的差异温度扩大了我们所经历的温度范围。(4)研究了夏季室内(20-25℃和室外(30-35℃))运动(测力计踩踏)时心率和摄氧量之间的关系以及生物反应运动期间进行了评估。虽然相同运动强度下的摄氧量没有变化，但户外运动时心率会增加，这可能是由于高温引起的皮肤血管扩张所致。在夏季的日常生活中，凉爽的室内温度突然变化。炎热的室外环境被认为是健康问题。
